According to a press release:
Due to the poor air quality in the Treasure Valley and the DEQ orange air quality alert suggesting that people stay inside, tonight’s K.D. Lang show has been canceled. After performing in Telluride, Colo., in similar conditions, K.D. Lang’s voice has already been compromised and she can not perform in today’s conditions.
